Cardiovascular disease risk assessment and multidisciplinary care in prostate cancer treatment with ADT: recommendations from the APMA PCCV expert network.

PURPOSE: Androgen deprivation therapy (ADT) is the mainstay approach for prostate cancer (PCa) management. However, the most commonly used ADT modality, gonadotropin-releasing hormone (GnRH) agonists, has been associated with an increased risk of cardiovascular disease (CVD). METHODS: The PCa Cardiovascular (PCCV) Expert Network, consisting of multinational urologists, cardiologists and oncologists with expertise in managing PCa, convened to discuss challenges to routine cardiovascular risk assessment in PCa management, as well as how to mitigate such risks in the current treatment landscape. RESULTS: The experts identified several barriers, including lack of awareness, time constraints, challenges in implementing risk assessment tools and difficulties in establishing multidisciplinary teams that include cardiologists. The experts subsequently provided practical recommendations to improve cardio-oncology care for patients with PCa receiving ADT, such as simplifying cardiovascular risk assessment, individualising treatment based on CVD risk categories, establishing multidisciplinary teams and referral networks and fostering active patient engagement. A streamlined cardiovascular risk-stratification tool and a referral/management guide were developed for seamless integration into urologists' practices and presented herein. The PCCV Expert Network agreed that currently available evidence indicates that GnRH antagonists are associated with a lower risk of CVD than that of GnRH agonists and that GnRH antagonists are preferred for patients with PCa and a high CVD risk. CONCLUSION: In summary, this article provides insights and guidance to improve management for patients with PCa undergoing ADT.

Perioperative and functional outcomes following robot-assisted partial nephrectomy: Descriptive analysis of Indian study group on partial nephrectomy database.

Introduction: There is an unmet need for high-quality data for Robot-assisted partial nephrectomy (RAPN) in the Indian population. Indian study group on partial nephrectomy (ISGPN) is a consortium of Indian centers contributing to the partial nephrectomy (PN) database. The current study is a descriptive analysis of perioperative and functional outcomes following RAPN. Methods: For this study, the retrospective ISGPN database was reviewed, which included patients who underwent RAPN for renal masses at 14 centers across India from September 2010 to September 2022. Demographic, clinical, radiological, perioperative, and functional data were collected and analyzed. Ethics approval was obtained from each of the participating centers. Results: In this study, 782 patients were included, and 69.7% were male. The median age was 53 years (interquartile range [IQR 44-62]), median operative time was 180 min (IQR 133-240), median estimated blood loss was 100 mL (IQR 50-200), mean warm ischemia time was 22.7 min and positive surgical margin rates were 2.5%. The complication rate was 16.2%, and most of them were of minor grade. Trifecta and pentafecta outcomes were attained in 61.4% and 60% of patients, respectively. Conclusions: This is the largest Indian multi-centric study using the Indian Robotic PN Collaborative database to evaluate the outcomes of robot-assisted PN, and has proven its safety and efficacy in the management of renal masses.

Determining age-specific prostate-specific antigen for healthy Indian men: A retrospective study.

Introduction: Prostate cancer usually affects older men and accounts for considerable cancer-associated mortality in men globally. In India, there is a rise in prostate cancer, and the published literature to determine age-specific prostate-specific antigen (PSA) is limited by a small sample size. The objective of our study was to determine age-specific PSA for Indian men based on a very large cohort of apparently healthy men undergoing health screening. Methods: This was a retrospective study using the hospital-based database of men who had undergone PSA blood tests as a part of health screening at two tertiary referral centers in South India between January 1, 2011, and August 31, 2018. Anonymous data were extracted, and statistical analysis was performed. Results: During this period, 99,386 men underwent PSA blood tests. Non-Indian patients and patients with PSA levels either <0.2 or >20 were excluded from the study, leaving 86,728 patients who were further analyzed. Seventy percent of patients were below 60 years of age, and the mean PSA for the study cohort was 1.2 ng/mL (standard deviation 1.74), with a median PSA of 0.7 ng/mL (interquartile range 0.4-1.1). The 95th percentile serum PSA level was 1.40, 1.70, 3.10, 5.80, 8.82, and 11.31 ng/mL for age groups of ≤40, 41-50, 51-60, 61-70, 71-80, and >80 years, respectively. The mean, median, and 95th percentile PSA reportedly increased for each decade of life (P = 0.0005). Conclusions: Results of this study indicated a positive correlation between serum PSA level and age in Indian men. These values are lower than the age-specific PSA defined for Caucasian men. These findings provide a basis for establishing new age-specific reference ranges of PSA for Indian men which will help in clinical decision-making.

Primary intrarenal yolk sac tumor.

Extragonadal germ cell tumors (EGGCTs) usually are not coexistent with a gonadal tumor, hence in a way, are primary and are rare. The origin of primary EGGCT is still a matter of debate. Herewith, we report a patient with primary intrarenal yolk sac tumor in a 43-year-old man. The purpose of this report is to add a rare tumor to the differential diagnosis of renal neoplasms.

Isolated Testicular Tuberculosis Disguised As a Testicular Tumor: A Report of a Rare Case.

Isolated testicular tuberculosis is rare, often diagnosed incidentally during histopathological examination due to its asymptomatic nature. We present a case of a 35-year-old male with a left testicular mass mimicking malignancy. Despite normal tumor markers and negative imaging for pulmonary tuberculosis, left inguinal orchiectomy revealed testicular tuberculosis. Diagnostic challenges are compounded by the disease's rarity and atypical presentation. Genitourinary tuberculosis's diagnostic complexity underscores the need for heightened clinical suspicion, particularly in tuberculosis-endemic regions. While orchiectomy may be necessary, this case underscores the importance of considering tuberculosis in testicular masses. Early recognition facilitates appropriate management and underscores the importance of diagnostic vigilance.

Paraurethral Leiomyoma: A Rare Entity Requiring Extensive Preoperative Counseling and Prompt Management.

Paraurethral leiomyoma is an exceptionally rare benign smooth muscle tumor adjacent to the female urethra, presenting diagnostic challenges due to nonspecific symptoms like urinary obstruction and dysuria. This case report details the clinical presentation, diagnostic workup, and surgical management of a 45-year-old woman with a paraurethral leiomyoma. Diagnosis involved clinical examination, imaging, and biopsy. The mass was excised via a perineal route without urethral injury, confirmed by histopathology. The patient recovered well, voiding without difficulty postoperatively. This case emphasizes the importance of thorough preoperative counseling, advanced imaging, and multidisciplinary collaboration in managing paraurethral leiomyomas.

Robot-Assisted Laparoscopic Radical Prostatectomy Utilizing Hugo RAS Platform: Initial Experience.

Background: The Hugo RAS™ is a newly launched robotic system for clinical use. This article provides the initial outcomes of patients undergoing radical prostatectomy with Hugo RAS. It also attempts to compare the outcomes with a similar set of patients undergoing the procedure with the DaVinci robotic systems. Methodology: Patients undergoing radical prostatectomy for biopsy-proven prostate cancer were included in this study. Institutional ethical approval was obtained, and patients were counseled preoperatively with informed consent. Both intra- and postoperative data were carefully recorded for the Hugo RAS. Patients who underwent radical prostatectomy in DaVinci robotic systems during a similar period were chosen to compare the outcomes of the Hugo systems in a nonrandomized study. Results: A total of 34 patients were included in this study wherein 17 radical prostatectomies were done in the Hugo RAS system and 17 in the DaVinci system were chosen to compare. The total operative time (210 vs 195 minutes) and dock time (190 vs 170 minutes) were similar between the two groups. An R0 or R1 resection and vesicourethral anastomosis were achieved in all cases. There were no notable intra- or postoperative complications in up to 1-month follow-up. Conclusion: The authors believe that the Hugo RAS platform is a safe robotic system for pelvic procedures such as radical prostatectomy, provides comparable results with existing robotic systems, and is a good addition to the existing arsenal of surgical robots.

Zero Ischemia Open Partial Nephrectomy in Crossed Fused Ectopic Kidney - A Rare but Real Challenge.

Crossed fused renal ectopia (CFRE) is a rare congenital anomaly with both kidneys located on the same side of the retroperitoneal space. Due to complex anatomy, any renal tumours arising from this congenital anomaly will require careful pre-operative planning and intra-operating management to ensure oncological clearance while maximizing renal function. In this clinical case, a 57-year-old lady was referred to our center with a left to right CFRE and a 10cmx8cmx8cm mass arising from the interpolar region of left ectopic kidney on a background of multiple medical co-morbidities including stage 3a chronic kidney disease (CKD). Careful pre-operative planning and optimization was done, including 3D reconstruction of CT images, and the decision was made to perform a zero ischemia open partial nephrectomy to give her kidneys the best fighting chance. She recovered well postoperatively with only a mild increase in creatinine and histopathology revealing a renal cell carcinoma. The case emphasizes the need for adequate pre-operative planning with the use of upcoming imaging modalities like 3D reconstruction for optimum planning to ensure the best postoperative outcomes.

Efficacy of Degarelix in the Neoadjuvant Setting in Managing Locally Advanced Prostate Cancer.

Background Prostate cancer holds a substantial presence in the global cancer landscape, and a considerable proportion of diagnoses occur at late stages, particularly in India. Management of locally advanced prostate cancer necessitates a multimodal treatment strategy. A critical part of this strategy is neoadjuvant androgen deprivation therapy, typically administered via luteinizing hormone-releasing hormone (LHRH) analogs. This study explores the potential of an alternative approach: neoadjuvant therapy with degarelix, an LHRH antagonist, and its impact on perioperative and postoperative outcomes in patients undergoing radical prostatectomy for locally advanced or high-risk prostate cancer. Methodology We conducted a retrospective, non-randomized clinical study at Apollo Hospitals in Chennai, India. Patients diagnosed with locally advanced or high-risk prostate cancer who underwent radical prostatectomy were included. Participants were patients treated with neoadjuvant degarelix and subsequent radical prostatectomy between March 2020 and June 2022. We excluded patients receiving radical radiotherapy, those switching from LHRH agonists to antagonists, and those contraindicated for androgen deprivation therapy due to existing comorbidities. For comparison, we selected a group from the institutional database who received conventional treatment (i.e., without neoadjuvant therapy). Results The study compared two groups, each with 32 patients. The groups had no significant difference in total operative duration and console times. The postoperative pathological assessment showed significantly lower margin positivity rates and notable pathological downstaging in the group receiving neoadjuvant degarelix compared to the control group. The incidence of node positivity, prostate-specific antigen levels at three months postoperative, and number of pads used per day at one month did not differ significantly between the two groups. Conclusions Our study suggests that neoadjuvant degarelix could notably enhance patient outcomes in locally advanced prostate cancer management. The benefits include improved symptom control, significant reductions in margin positivity rates, and facilitated surgical procedures. Neoadjuvant degarelix therapy could potentially enhance the feasibility of the surgical intervention in locally advanced prostate cancer management, thus suggesting a promising pathway for improved patient care.

Clinical outcomes of laparo-endoscopic single-site surgery radical nephrectomy.

INTRODUCTION: The conventional laparoscopic surgery is now paving way to the new technologies including robotic and laparoscopic single-site surgery (LESS). We present our updated experience on LESS radical nephrectomy (LESS-RN). PATIENTS AND METHODS: The data from patients undergoing LESS-RN in our two institutions were reviewed along with various clinical and pathological parameters. RESULTS: Between 2008 and 2011, 42 LESS-RN were performed (right = 22, left = 20) with mean (range) age and BMI of 63.7 (33-86) years and 25.1 (18-38.6) kg/m(2), respectively. In addition to the instruments in the single port, one extra 3-mm needlescopic instrument was required in 19 patients (right = 17, left = 2). In three patients, two additional 5-mm trocars and instruments were required. None required open conversion. The recorded adverse events include one bowel injury (intraoperative closure without the need for stoma), one postoperative bleeding requiring blood transfusion, one prolonged ileus, and one deep venous thrombosis. The resected specimens revealed pT1a (n = 3), pT1b (n = 33), pT2a (n = 4), and pT3b (n = 2) tumors. The finding of pT3b was incidental rather than planned procedure. None of the patients had positive margins. CONCLUSION: LESS-RN has proven to be feasible and safe. Beyond cosmesis, further advantages of this approach need to be addressed by randomized trials.

Feasibility of minimally invasive radical prostatectomy in prostate cancer patients with high prostate-specific antigen: feasibility and 1-year outcomes.

OBJECTIVES: Urologists are cautious to offer minimally invasive radical prostatectomy in prostate cancer patients with high prostate-specific antigen (and therefore anticipated to have locally advanced or metastatic disease) because of concerns regarding lack of complete cure after minimally invasive radical prostatectomy and of worsening of continence if adjuvant radiotherapy is used. METHODS: A retrospective review of our institutional database was carried out to identify patients with PSA ≥20 ng/mL who underwent minimally invasive radical prostatectomy between January 2002 and October 2010. Intraoperative, pathological, functional and short-term oncological outcomes were assessed. RESULTS: Overall, 233 patients met study criteria and were included in the analysis. The median prostate-specific antigen and prostate size were 28.5 ng/mL and 47 mL, respectively. Intraoperative complications were the following: rectal injury (0.86%) and blood transfusion (1.7%). Early postoperative complications included prolonged (>6 days) catheterization (9.4%), hematoma (4.7%), deep venous thrombosis (0.86%) and lymphocele (5.1%). Late postoperative complications included cerebrovascular accident (0.4%) and anastomotic stricture (0.8%). Pathology revealed poorly differentiated cancer in 48.9%, pT3/pT4 disease in 55.8%, positive margins in 28.3% and lymph node disease in 20.2% of the cases. Adverse pathological findings were more frequent in patients with prostate-specific antigen >40 ng/mL and (or) in those with locally advanced disease (pT3/pT4). In 62.2% of the cases, adjuvant radiotherapy was used. At 1-year follow up, 80% of patients did not show evidence of biochemical recurrence and 98.8% of them had good recovery of continence. CONCLUSION: Minimally invasive radical prostatectomy might represent a reasonable option in prostate cancer patients with high prostate-specific antigen as a part of a multimodality treatment approach.

Evaluation of Hugo RAS System in Major Urologic Surgery: Our Initial Experience.

Background: The Hugo RAS is a newly launched robotic system for clinical use. This article provides the initial experience of the authors using Hugo RAS in urologic procedures. Methodology: Patients undergoing major urologic procedures, including nephrectomy and prostatectomy, were included in this prospective clinical trial. Institutional ethical approval was obtained, and patients were counseled preoperatively with informed consent. Both intraoperative and postoperative data were carefully recorded. Results: A total of seven patients were included in this initial study. This includes radical prostatectomy (n = 3), simple prostatectomy (n = 1), radical nephrectomy (n = 1), and simple nephrectomy (n = 2). The total operative time, port placement time, time to dock the ports, blood loss and length of hospital stay, and 30-day morbidity and mortality were recorded. There were no intraoperative or postoperative complications up to 1 month follow-up. Conclusion: From the early experience with the Hugo RAS™ platform, it appears to be a safe robotic platform for major urologic procedures and is a good addition to the existing arsenal of surgical robots.

Robot assisted laparoscopic adrenalectomy: Should this be the new standard?

INTRODUCTION: Minimal invasive surgeries (MIS) for large size adrenal tumors are still debatable. The objective is to evaluate the contemporary peri- and post-operative outcomes of patients undergoing (open = OA, laparoscopic = LA, and robotic = RA) adrenalectomies in three institutions. MATERIALS AND METHODS: Retrospectively gathered peri- and post-operative data of 235 patients, underwent adrenalectomy at three Institutions over a 7-year period (2013-2020) were analyzed. All patients underwent thorough radiological and endocrine workup. RESULTS: Two hundred and thirty five patients who underwent adrenalectomy (OA (n = 29), LA (n = 146), and RA (n = 60)) were assessed. OA (n = 29) versus Minimally invasive surgery (n = 206) showed significant differences (median, p value) in larger tumour size, cm (9.4 vs 5, (p = 0.0001)), longer operative time, mins (240 vs 100, (p = 0.0001)), longer hospital stay, days (8 vs 3,(p = .0001)), Higher readmission rates (14% vs 1.9%), higher blood loss, ml (400 vs 100, (p = 0.0001)) requiring blood transfusion (14% vs 4.3%) (p = 0.03), higher intraoperative complication (21% vs 6%) (p = 0.0004), and post op complications (17% vs 5.3%) (p = 0.01). Amongst the MIS (RA vs LA), RA appeared be have better outcomes in terms of shorter operative time, less blood loss and less intra operative complications with a p value <0.05. These results were consistent for the assessment of patients who had ⩾6 cm tumor size. The postoperative complication rates were lowest with RA (3.3%) compared to OA (17%) and LA (6.1%). CONCLUSIONS: Contemporary practice of adrenalectomy shows that robotic adrenalectomy is safe and effective irrespective of the tumor size.

Influence of tumor size in the progression of venous tumor thrombus in renal cell carcinoma: A 7-year single-center experience.

Objective: The objective of the study is to describe the perioperative outcomes, disease-specific, and overall survival status in patients diagnosed with renal cell carcinoma with inferior vena cava (IVC) tumor thrombus. Patients and Methods: We did a retrospective analysis of all patients who underwent radical nephrectomy along with IVC thrombectomy from the year 2013 to 2020. Mayo's classification was used to stratify the level of IVC thrombus. Demographic, perioperative, histopathology data, complications, and survival status were analyzed. Results: Total number of patients included in the study was 39, (Male: Female = 84.6%: 15.4%). Median age of patients was 58 (interquartile range [IQR] 50-63) years. Median size of renal tumor (in cms) was 9.5 (IQR 7.5-12), 8 (IQR 7-11.5), 8.5 (IQR 7-11.75), and 11 (IQR 9.5-11) (P = 0.998) in level 1,2,3, and 4 tumors, respectively. Clear cell variant was seen in 32 patients (82%) with R0 resection in 17 patients. Twelve patients (30.7%) had systemic metastasis on presentation. The overall mean survival time was 66.4 months with 95% confidence interval (CI) (52.4-80.5 months). Mean recurrence-free survival is 76 months with (63-90) CI of 95%. Mean survival in patients who presented with metastasis is 47 months with 95% CI (52.4-80.5). Perioperative mortality rate was 5.12% in this study. Conclusion: The tumor size does not have an influence on the progression of tumor thrombus into IVC. Significant difference in survival was observed between different levels of thrombus with high mortality in level four tumors.

The Chennai port closure method: A novel simple technique for laparoscopic port closure.

PURPOSE: Large-size ports used for laparoscopic and robotic procedures will require appropriate closure to reduce the probability of trocar site complications including hematoma and hernia. Closure of these ports is done by various methods like the open method extending skin incisions, S-retractor, Carter Thomason method, and so on. Chennai port closure (CHC) method, a novel technique that had been in practice in our unit for more than 2 years, ensures direct visualization of the suture placement, and hence, the abdominal wall fascia and peritoneum are secured. MATERIALS AND METHOD: We herein describe an easy technique for fascial closure in port size (≥ 10 cm) after minimally invasive surgery, including both laparoscopic and robotic procedures, using a cobbler needle in 151 patients in the study period between February 2017 and March 2020 for various urological procedures. This technique was done before the introduction of the trocar sheath and ensures direct visualization of the abdominal fascial closure. RESULTS: There were no major intraoperative events, additional operating time, and need for any costly instruments. No bowel injuries or trocar site hernias were documented during a mean follow-up of 28 months. Presently, this technique is used by many surgeons in our hospital without much difficulty. CONCLUSION: The Chennai port site closure technique is an effective, simple, easy-to-apply, and safe procedure.

Prevalence of Vitamin D Inadequacy in Urolithiasis Patients.

Introduction The role of vitamin D in kidney stone disease is unclear. Current evidence and existing studies are inconsistent and inconclusive. The objective of this study is to assess the prevalence of vitamin D (VD) inadequacy (VDI) and metabolic abnormalities in urolithiasis patients presenting to a tertiary care center. Materials and methods This is a prospective case-control study of 200 patients divided into two groups - Group 1: 100 urolithiasis patients (case group), and Group 2: 100 non-urolithiasis patients (control group) - which was conducted from January 2016 to January 2017. Demographic, clinical data, parathyroid level, serum 25-hydroxy VD [25(OH)D], and metabolic stone work-up were recorded and analyzed.  Results Patient demographics were comparable in both groups. The prevalence of vitamin D inadequacy in urolithiasis patients was 95% as compared to 57% in the control group. The mean value ± SD of serum vitamin D in urolithiasis patients (16.5 ± 8.6 ng/mL) was significantly lower than in non-urolithiasis patients (28.7 ± 8.3 ng/mL) (p = <0.0001). Thirty-seven percent of the patients were recurrent stone formers. Hyperparathyroidism was observed in 77% of the patients and 71% of them were secondary to VDI. Conclusion Urolithiasis patients were found to have an increased prevalence of deficient VD related to secondary hyperparathyroidism.

A Single Tertiary Center Experience in a South Asian Population: Does Tobacco Use Influence Bladder Cancer?

Introduction Tobacco use, especially cigarette smoking, is a well-documented risk factor for cancer; however, its specific effect on bladder cancer has not been clearly defined. This study aimed to determine the association between tobacco use and bladder cancer in a South Asian population. Materials and methods We conducted a retrospective review of the medical records of 64 patients diagnosed with bladder tumors from February 2018 to March 2020. Patients included in the study were surveyed via a questionnaire regarding tobacco use. All patients received transurethral resection of the bladder tumor, and we analyzed histopathological and clinical outcomes. Results Our study population's median age was 57 years, and the study included twice as many male patients as female patients. Most patients (n=45; 70%) reported not using tobacco products, and 19 patients (30%) reported tobacco use. Thirty-five of 45 nontobacco users (78%) had high-grade cancer, and 10 (22%) had low-grade cancer. Among the tobacco users, 10 (52%) had high-grade cancer, and nine (48%) had low-grade cancer. Conclusions According to our findings, a substantial cohort of bladder cancer patients is not tobacco users, and high-grade bladder cancer was more common to people who are not tobacco users. Other environmental factors play a key role in developing bladder cancer in our South Asian study population. Prevention efforts should focus on reducing bladder cancer risk factors.

Carcinosarcoma of the Prostate Masquerading as Benign Prostatic Enlargement: Lesson Learned.

Primary carcinosarcoma of the prostate is an extremely rare and aggressive malignancy. We report a patient who presented with obstructive symptoms and without a history of radiation, prior adenocarcinoma, or androgen deprivation therapy. Transurethral resection of the prostate was performed. Histopathology and immunohistochemistry revealed a confirmatory diagnosis of de novo carcinosarcoma of the prostate. The case is described for its rarity and masquerading nature.

Day-case robot-assisted laparoscopic surgery: Feasibility and safety.

OBJECTIVE: The delivery of surgical services has undergone a shift in the past decade with increasing numbers of surgeries being performed in the daycare setting. Implementing a minimally invasive surgical approach with a robot with an enhanced recovery protocol permits robot-assisted laparoscopic surgeries (RALS) to be performed as a day-case (DC) procedure. This study aimed to assess the feasibility and safety of DC surgery according to our experience. MATERIAL AND METHODS: In this prospective observational study, 43 patients underwent DC RALS performed by a single surgeon over 18 months [simple nephrectomy (n=7), radical nephrectomy (n=15), radical nephrectomy with para-aortic lymphadenectomy (n=5), and adrenalectomy (n=5)]. In addition, reconstructive urological procedures that included pyeloplasty (n=9), ureteroureterostomy (n=1), and bladder diverticulectomy with ureteric re-implantation (n=1) were performed as DC surgeries during this study period. RALS was performed in the standard way with an enhanced recovery pathway of care for DC. We collected data regarding the demographic information, medical comorbidities, preoperative outcomes, intraoperative outcomes, complications, length of stay, and readmission rates. The data were analyzed and evaluated. RESULTS: All the patients (100%) were successfully discharged on the same day with no major complications (Clavien-Dindo grade>I). The readmission rates were 0%. CONCLUSION: DC RALS are safe and feasible with an enhanced recovery protocol. With adequate protocols in place, these surgeries might prove to be better than the available minimally invasive techniques and can become the standard of care in the future.
